a moment equations method was performed to study the reversible chain transfer catalyzed polymerization (rtcp) of styrene in 80°c. to do this, a kinetic scheme containing conventional free radical polymerization reactions and equilibrium reactions of rtcp was assumed. after obtaining mass balance equations, three moment equations were defined for free and dormant radicals and dead chains. monom...

RTP, the Real Time Transport Protocol, has gained widespread acceptance as the transport protocol for voice and video on the Internet. Its companion control protocol, the Real Time Control Protocol (RTCP), is used for loose session control, QoS reporting, and media synchronization, among other functions. The RTP specification describes an algorithm for determining the RTCP packet transmission r...

In this paper, we outline an architecture which enables the real-time delivery of continuous media over the Internet using the Real-time Transport Protocol (RTP). We present our implementation of RTP with its control protocol RTCP. RTCP feedback reports are used by our adaptive rate controller to help reduce congestion. Then, we assess the functionality of RTP and its suitability for the future...

An MPEG-2 Transport Stream (TS) is a standard container format used in the transmission and storage of multimedia data. Unicast/ multicast MPEG-2 TS over RTP is widely deployed in IPTV systems. This document defines an RTP Control Protocol (RTCP) Extended Report (XR) block that allows the reporting of MPEG-2 TS decodability statistics metrics related to transmissions of MPEG-2 TS over RTP. The ...

Multicast applications and network monitors can potentially benefit from the ability to infer the loss rates along links within a multicast tree. Estimators, known generically by minc, or multicast inference of network characteristics, have been developed to provide this ability. They consider multicast data packets to be probes, and conduct inference based upon reports of which probes reached ...

This memorandum describes RTP, the real-time transport protocol. RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services. RTP does not address resource reservation and does not guarantee quality-of-service for real-time services. The data transport is augmented ...

Over the last few years, the demand for real-time multimedia services has been growing progressively so that video streaming applications are expected to be dominant in future communications systems, and most of them using RTP/RTCP protocols. This paper presents an evolved tool-set for video streaming QoS evaluation in simulated environments using such protocols. We have designed a new NS-2 mod...
